well, i started out doing 6 PF style jars and theyre still in the incubation stage. iv got 4cc's of spores left (hope thats enough for 2-3 1quart jars) and decided im gonna try a grain casing grow with them. just had a few questions.

as far as tyvek goes, i hear everyone say you can get it for free. im just kind of wondering how heh. i understand the post office carries envelopes made from tyvek, i just figured they costed money (most of their packing supplies do). if theyre free, what do you do exactly? go in and grab a handfull and walk out? lol

secondly, is a pressure cooker absolutely necessary for a grain casing op? im trying to avoid buying more stuff since this is all on a budget, that and im running out of space hehe. i read about a fractional sterilization method and was curious about the success rate of it.

id like to do the grain casing method, seems so much simpler then doing cakes and looks like it yields a lot more (trying to grow a lot to give to my dad and his 60 year old hippy friends.)

any suggestions are appreciated, pics to come soon of my first attempts. i read all teks like a priest reads his bible, just trying to sort out the variables

Go to the post office and ask for tyvek priority mail envelopes. I dunno how many you can get for free though. I just asked for 10, he went to the back room and got them for me. 10 is far enough for anyone's needs though i think. You could probably do 80 quart jars with 10 of them. I did 12 pint jars per envelope. and you can do 16 1/2 pints per envelope.

thanks for the info. im probably going to try a G2G transfer so i can get more out of the 4ccs i have left.

what about the fractional sterilization method? would really like to know how effective it is. i dont mind if it takes a few days to do. buying a pressure cooker is out of the question right now since im broke and have bills due.
